A South Florida high school is in the national spotlight after a gunman attacked Wednesday afternoon, in the deadliest school shooting since Sandy Hook.

As the story develops, here’s a look at some details by the numbers:

17 people killed

Broward County Sheriff Scott Israel told media on Wednesday that the total number included both students and adults. Of those, two were shot outside the school, 12 inside and one person was shot standing on a nearby street corner. He said two additional people were taken to hospitals and later died.

Israel said the count could rise. Police have not officially identified the victims yet.

2 victims with Long Island roots

At least two of the school staff members who were fatally shot grew up on Long Island. Scott Beigel, 35, a teacher who was shot as he was trying to lock a classroom door to shield students, grew up in Dix Hills.

Junior varsity football coach Aaron Feis, 37, lived in West Islip as a boy. Feis died in a hail of gunfire after he threw himself in front of students as a human shield, according to news reports.

16 hospitalized

Doctors said 16 people were taken to hospitals to be treated. Two of them died at the hospital. The total number of injured people has not been confirmed.

1 weapon

Police said in media briefings that only one weapon, an AR-15 rifle, was used in the attack. The weapon was later found when police arrested suspect Nikolas Cruz, 19.

17 counts of premeditated murder

Authorities charged Cruz with 17 counts of premeditated murder, one for each person who was killed. Cruz was first taken to a hospital after his arrest, then transported to a Broward County jail early Thursday and booked, according to the Sun-Sentinel.

3,000 students and 129 teachers affected

Marjory Stoneman Douglas High School is one of the largest high schools in Broward County, according to the Sun-Sentinel. It was built in 1990 and serves about 3,000 students in grades 9 to 12 with about 129 teachers. The school will remain closed through the end of this week, school officials announced.

30 mass shootings this year

Definitions vary on what constitutes a mass shooting, with inconsistent numbers reported among the FBI, Congress and advocacy groups.

Gun Violence Archive, a nonprofit that tracks gun incidents, defines a mass shooting as a single event where four or more people are injured or killed, not including the shooter. Their records include 30 such cases in 2018.

11 school shootings this year

Again, statistics depend on what definition you use. Gun Violence Archive includes incidents that take place on school property when students and staff are present. Suicides are generally not included in any of GVA’s updating statistics.

The organization said that including the Parkland shooting, there have been 11 shootings with injuries or deaths at schools in 2018.
